Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. Installation automatically refreshes pre-existing Todoist CLI skills in supported AI-agent directories. This is a first-party agent-extension lifecycle action, not a confirmed malicious attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-27T15:48:58.057Z - **Finished:** 2026-09-27T15:50:21.213Z - **Download time:** 1027 ms - **Static scan time:** 1238 ms - **AI review time:** 80890 ms - **Total time:** 83156 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically refreshes pre-existing Todoist CLI skills in supported AI-agent directories. This is a first-party agent-extension lifecycle action, not a confirmed malicious attack. - **Trigger:** npm postinstall runs during package installation. - **Impact:** Existing agent skill content can change without an explicit CLI command at upgrade time. - **Evidence paths:** package.json, scripts/postinstall.js, dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/index.js, dist/lib/skills/create-installer.js - **Review source:** ai\_review - **Reviewed:** 2026-09-27T15:50:21.213Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook calls the installed-skill updater, which detects existing skill files and rewrites generated skill content. - **Rationale:** Automatic postinstall mutation of already installed AI-agent skills warrants a warning under the lifecycle policy. The observed scope is package-owned skill content and no concrete malicious chain was found. - **Files touched:** ~/.claude/skills/todoist-cli/SKILL.md, ~/.codex/skills/todoist-cli/SKILL.md, ~/.copilot/skills/todoist-cli/SKILL.md, ~/.cursor/skills/todoist-cli/SKILL.md - **Network endpoints:** https://api.todoist.com/api/v1/user ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package declares an automatic postinstall hook., The postinstall entry invokes installed-skill updates., Updates are limited to skills already detected as installed., Skill installers target several agent configuration directories, including Claude Code and Codex., The installer creates parent directories and rewrites the skill file., Extension dispatch runs a selected extension with the inherited process environment. - **Evidence against:** No hidden remote payload loader, eval use, or unrestricted credential destination was found in the inspected paths., The automatic skill updater checks for an existing installation before updating it., The auth migration endpoint is Todoist-owned. ## Affected versions and remediation This report applies to @doist/todoist-cli@5.4.2. - Review the evidence and your use of @doist/todoist-cli@5.4.2 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
